Background & Objective: In Iranian women, the age of breast cancer is 10-20 years earlier than women living in developed countries. Moreover, HPV infection has increased among Iranian women and it is more common compared to European women. The purpose of the present study is to investigate the role of HPV as a potential risk factor for breast cancer at younger ages.Materials & Methods: This study is a case-control study that was performed on 46 specimens of breast cancer tissue and 46 samples of normal breast tissue with no malignancy. In coordination with the pathology laboratory of Poursina Hospital (Rasht, Iran), samples of breast cancer pathology templates that were available in the laboratory archives were selected after a preliminary examination of the accuracy of tissue diagnosis. After that, a tissue incision was prepared with H&E staining and the cancer diagnosis was again confirmed by a pathologist. Samples were cut with a microtome with disposable blades. Then the tissue sample was deparaffinized and its DNA was extracted. The data were analyzed by SPSS software version 21 (IBM SPSS, Armonk, NY, USA) using Chi-square, T-test, variance analysis and logistic regression.Results: The results showed a significant difference between the two groups of women with breast cancer and without malignancy in the age of first pregnancy and gravidity. There was a significant difference in human papillomavirus type 16 infection between the two groups with breast cancer and without malignancy. The logistic regression model examined the effect of all variables and showed that infection with human papillomavirus type 16 increased the risk of breast cancer by 4.6 times, taking into account other variables.Conclusion: The present study, independent of other studies, showed that human papillomavirus type 16 could be a risk factor for breast cancer. If the virus is found in an individual, it is recommended that the patient be monitored frequently and more detailed examinations for breast malignancies be performed.

Background & Objective: Cervical cancer is the second most prevalent cancer in women worldwide and is one of the leading causes of deaths in women with cancer in developing countries. The most well-known cause of this cancer is being infected with human papillomavirus (HPV). This study aimed at evaluating the concurrent methylation pattern of the human papillomavirus genome in studying the DAPK1 gene as a diagnostic biomarker in cervical cancer.
Materials & Methods: This study was approved by the Ethics Committee of the Islamic Azad University of Tabriz under the following ethical code, i.e., IR.IAU.TABRIZ.REC1398.001.This case-control study was conducted on 150 paraffin-embedded samples (75 marginal samples and 75 cervical cancer tissue samples) taken from women with cervical cancer. After extracting the total DNA, spectrophotometry and electrophoresis were performed on agarose gels to determine the quantity and quality of the extracted DNA. Changes in the DAPK1 gene methylation pattern were examined using High Resolution Melt Analysis Curve Method.
Results: The changes in theDAPK1 gene expression in the cervical tumor tissues increased compared to the marginal tissues, indicating a statistically significant difference (P < /em><0/0001).
Conclusion: The results of the current study showed that the DAPK1 gene can be introduced as a possible prognosis for cervical cancer diagnosis and treatment. However, more extensive studies with more samples are needed to be carried out.
